Apparatus and method for preventing queue overflow for hard disk drive protection in computer system
Patent number: 8516168Abstract: A queue overflow prevention method and apparatus for Hard Disk Drive (HDD) protection in a computer system is provided. The queue overflow prevention method includes measuring acceleration information of the system, determining if the system is in a stable status or an unstable status using the acceleration information, and, while the system is in the unstable status, restricting the generation of a disk Input/Output (I/O) request.Type: GrantFiled: April 13, 2010Date of Patent: August 20, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Bum-Keun Kim -
Patent number: 8416514Abstract: Provided are a lens unit, a lens assembly, a camera module, a method of fabricating the camera module and the lens assembly, a method of fabricating an optic member, and an apparatus of fabricating the optic member. The lens unit comprises a lens portion and a supporting portion. The lens portion has a curved surface. The supporting portion extends from the lens portion. The supporting portion comprises a protrusion or a recess. The method of fabricating the optic member comprises injecting a resin composition inside a mold die, pressing the resin composition; and irradiating light onto the resin composition. Due to the pressure, shrinkage of a photo-curable resin composition can be reduced, and thus, the lens unit comprising the protrusion or recess can be easily fabricated.Type: GrantFiled: January 8, 2009Date of Patent: April 9, 2013Assignee: LG Innotek Co., Ltd.Inventors: Bum Keun Kim, Jin Han Song, Myoung Jin An, Kee Tae Um, Chan Kwon Lee
